Innovative, easy to use HMI
Each ControlMaster has an innovative HMI at the
heart of its operation, providing a common link
with other instrumentation products from ABB. So, if
you know one, you know them all. Operation is so easy
that you will be impressed by the efficiency of it all.
Advanced controls and functionality
On each of the 4 new ControlMaster instruments,
higher levels of functionality are right at your finger
tips. Features packed in include math, totalization
and a frequency input, logic, gain scheduling, split
output, valve control and real time alarms.
pPI predictive control enables processes with long dead
times to be easily controlled. Simple configuration needs
only three parameters - proportional band, integral time and
dead time. Adaptive control means automatic adjustment
of control response to correct changing process dynamics.
Valuable where processes have varying or uncontrolled
types of load, it provides continuous tuning for optimum
control efficiency 24/7. Dual loop control independently
manages two separate processes. The loops operate
entirely independently while ControlMaster's flexibility
and functionality provides interlock and interaction
between both if required. Processes can be displayed
simultaneously on one screen without compromizing data.

Communications protocols
Ethernet communications provide high levels of connectivity.
Remote process monitoring is made easy via the integrated
web server. A ControlMaster can send emails upon alarm
conditions or critical process status, providing instant
notification to a plant supervisor. Modbus communications
(TCP or RTU) enable rapid connection to PLCs and control
systems. Modbus also provides simple, fast connection
of multiple ControlMasters to a ScreenMaster recorder
to create a multipoint control and data logging system.
